Invention execution mode
Fig. 1, has shown the cardinal principle layer structure of HTS conductor according to an embodiment of the present invention in figure.HTS conductor comprises base material 10, is covered with the resilient coating 12a of base material 10, and then HTS layer 14a be covering layer 16a (being generally layer of precious metal) and stabilized zone 18a (being generally base metal).
Base material 10 is generally Metal Substrate, is generally the alloy of at least two kinds of metallic elements.
Specially suitable substrate material comprises nickel based metal alloy, and example is the alloy of inconel class as is known.Inconel has required thermal property, chemical property and engineering properties, comprises the coefficient of expansion, thermal conductivity, Curie temperature, hot strength, yield strength and elongation.These metals can be buied with the form of the band of reeling conventionally, and particularly suitable is manufactured HTS band, manufacture HTS with time conventionally adopt the band processing of (reel-to-reel) of roll-to-roll.
Base material 10 is generally the banded structure that length-width ratio is very large.For example, bandwidth is about 0.4-10 centimetre conventionally, and belt length is at least about 100 meters conventionally, is more generally approximately greater than 500 meters.In fact, the length of the base material 10 of superconductive tape that embodiment of the present invention provides is about 1 kilometer or longer.Therefore, base material can have sizable length-width ratio, is not less than 10 3and even, be not less than 10 4.Some embodiment is larger, and length-width ratio is 10 5or larger.In this article, term ' length-width ratio ' represents the ratio of base material or the length of band and its vice-minister's size (width of base material or band).
In one embodiment, base material is processed, made it have and deposit subsequently the required surface nature of each composition layer of HTS band.For example, effects on surface carries out slight polishing, to reach required evenness and surface roughness.In addition, can on twin shaft, form texture by for example known RABiTS (base material of the biaxial texture (texured) that roller is auxiliary) technical finesse base material, this is understandable to those skilled in the art.
Refer now to resilient coating 12a, this resilient coating can be individual layer, or more generally multiple film, consists of.The most typically say, resilient coating comprises that twin shaft has the film of texture, and the crystal texture of this film conventionally crystallographic axis in membrane plane or outside membrane plane is arranged.Can form this biaxial texture by IBAD.Those skilled in the art can understand, IBAD is the acronym of ion beam assisted depositing, this technology can be used for forming the resilient coating that suitably has texture valuably, has the resilient coating of texture to be used for forming subsequently the HTS layer with required crystal orientation, to obtain good superconducting property by this.Magnesium oxide is the material that IBAD film is selected conventionally, can be

, for example
Figure G04818114319960422D000042
.According to No. 6190752 institute of United States Patent (USP), define and describe, IBAD film has rock salt shape crystal structure, and described patent documentation is incorporated herein by reference.
Resilient coating can comprise other layer, for example, between IBAD film and base material, and the barrier film directly contacting with these two.In this, barrier film should be formed by the oxide of yittrium oxide and so on, is used for base material and IBAD film to separate.Barrier film also can be formed by the non-oxidized substance of silicon nitride and carborundum and so on.The method of suitable deposition barrier film comprises chemical vapour deposition and comprises the physical vapour deposition (PVD) of sputter.Conventionally the thickness of barrier film is about
Figure G04818114319960422D000043
.In addition, resilient coating also can comprise the epitaxial film being formed on above IBAD film.About this point, epitaxial film can increase the thickness of IBAD film effectively, wishes mainly to use the material identical with IBAD layer (for example MgO) to make.
In using the execution mode of MgO base IBAD film and/or epitaxial film, between MgO material and the material of superconductor layer, can there is lattice mismatch.Therefore, resilient coating also can comprise another layer of buffer film, reduces HTS layer and IBAD film below and/or the lattice constant mismatch between epitaxial film especially by this buffer film.This buffer film can be formed by the material of YSZ (zirconia of stabilized with yttrium oxide) ruthenic acid strontium, lanthanum manganate and so on, and the ceramic material by perovskite structure forms conventionally.Can be by various physical vapor deposition techniques deposition buffer films.
Although mainly concentrate on above by the texture forming method of IBAD and so on and realize biaxial texture formation film in buffering lamination,, also can originally form biaxial texture with it at substrate surface.In the case, resilient coating is having epitaxial growth on the base material of texture conventionally, with the twin shaft remaining in resilient coating, forms texture.Form twin shaft having the method for the base material of texture is a method that is called RABiTS (the auxiliary twin shaft of roller has the base material of texture) in this area, and the method is generally understood in this area.
Described high-temperature superconductor (HTS) layer 14a is selected from any high temperature superconducting materia under higher than liquid nitrogen temperature 77K with superconducting property conventionally.These materials can comprise for example YBa 2cu 3o 7-x, Bi 2sr 2ca 2cu 3o 10+y, Ti 2ba 2ca 2cu 3o 10+yand HgBa 2ca 2cu 3o 8+y.One class material comprises REBa 2cu 3o 7-x, wherein RE is rare earth element.In previous materials, preferably use the YBa that is commonly called YBCO 2cu 3o 7-x.HTS layer 14a can be by comprising that any one method that thick film forming technology and film form technology forms.Preferably the thin film physics vapor deposition techniques of pulsed laser deposition (PLD) and so on can be used for to high deposition rate, or the processing for lower cost and large surface area by chemical vapour desposition technology.Conventionally, the thickness of HTS layer is about 1-30 micron, is more generally about 2-20 micron, for example, be about 2-10 micron, to reach the required current rating of HTS layer 14a.
Conventionally with covering layer 16a and stabilized zone 18a, carry out electric stabilisation, help prevent HTS that " burning " occurs in actual use.Specifically, when cooling, when breaking down or surpassing critical current density thereby HTS layer and do not have resistance in superconducting state, layer 16a and 18a help electric charge Continuous Flow to cross HTS conductor.Conventionally noble metal is prevented from, between one or more layers stabilized zone and HTS layer 14a, undesirable interaction occurs as covering layer 16a.Conventionally gold, silver, platinum and palladium for noble metal.Because silver-colored cost is low, be convenient to processing, conventionally use silver.Conventionally covering layer 16a is made enough thickly, in case the component of stabilized zone 18a, to HTS layer 14a, undesirable diffusion occurs, but in order to reduce costs (raw material and processing cost), conventionally made very thin.The thickness of covering layer 16a is about 0.1-10.0 micron conventionally, for example, be about 0.5-5.0 micron.Can, by various deposition techniques covering layer 16a, comprise the physical vapor deposition of dc magnetron sputtering and so on.
According to the specific features of embodiment of the present invention, with stabilized zone 18a, cover superconductor layer 14a, with embodiment shown in Fig. 1, cover covering layer 16a specifically, and directly contact with covering layer 16a.Stabilized zone 18a as protective layer/shunting layer to improve the stability of harsh and unforgiving environments condition and superconductivity quench.This layer is normally fine and close and be thermal conductance and electrical conductance, is used for shunt current when superconductor layer failure.Conventionally, use the middle junction condensation material of solder flux or scolder and so on that preformed copper strips is laminated on superconductive tape, form these layers.Other technology is mainly physical vapor deposition, is generally sputter.Yet these application technology costs are very high, be not specially adapted to business large-scale production operation.According to the specific features of execution mode, stabilized zone 18 forms by plating.According to this technology, can electricity consumption be plated in the quick material thick-layer that forms on superconductive tape, galvanoplastic are a kind of lower-cost methods, can effectively manufacture the compacted zone of heat-conducting metal and conducting metal.According to a feature, during deposition stabilized zone, do not need to rely on and use middle close binder (for example fusing point is less than about the solder layer (comprising solder flux) of 300 ℃).
Conventionally superconductive tape is immersed in the solion of the metal that comprises needs depositions and electroplates (also referred to as electro-deposition).The surface of band is connected with external power source, and electric current enters solution by surface, makes metal ion (M z-) and electronics (e -) reacting forms metal (M).
M z-+e -=M
Covering layer 16a is as the crystal seed layer of deposited copper thereon.For example, in the situation that concrete electroplated stabilizer metal immerses superconductive tape in the solution (, copper-bath) of copper ions conventionally.Foundation is electrically connected to covering layer 16a's, and electric current passes through wherein, and Cu reacts on the surface of covering layer 16a 2++ 2e -Cu.Covering layer 16a as negative electrode, makes metal ion be reduced to Cu metallic atom deposition on tape in solution.On the other hand, in solution, insert the anode of cupric, in anode generation oxidation reaction, make copper ion enter solution, and then reduce deposition occurs on negative electrode.
In the situation that there is no side reaction, in electrolytic process, be transported to the electric current of conductive surface and the amount of plated metal be directly proportional (Faraday's laws of electrolysis).By this relation, can control at an easy rate the quality that forms stabilized zone 18a, thereby control its thickness.
Although normally with regard to copper, should be noted that also and can use other metal, comprise aluminium, silver, gold and other thermal conductivity and conductive metal above.Yet, need to be to reduce with base metal the total material cost that forms superconductive tape conventionally.
Although the side that description above and Fig. 1 have described by electroplating at superconductive tape forms stabilized zone 18a, should note also can on the contrary first type surface of superconductive tape, being coated with, in fact, can total be coated with and this structure is encapsulated.About this point, Fig. 2.
Fig. 2 is the sectional view that shows another execution mode of the present invention, wherein whole superconductive tape is all sealed by the first stabilized zone 18a and the second stabilized zone 18b that is positioned at superconductive tape corresponding main surfaces, the first stabilized zone 18a and the second stabilized zone 18b combine at the side surface of superconductive tape, conventionally form protruding side or side bridge 20a and 20b.In refrigeration, break down, in the situation such as superconduction quencher (superconductivity quench), need this special structure further improve electric current and further protection HTS layer 14a.By forming the first stabilized zone 18a and the second stabilized zone 18b, the cross-sectional area of deposited stabilized zone is doubled, thereby being obtained, improves current capacity.Can between stabilized zone 18a and 18b, provide electric continuity by side bridge portion 20a and 20b.In this regard, can need side bridge portion 20a and 20b to there is genuine radius of curvature, form convex surface, thereby can further reduce the charge accumulated of HTS power equipment when high pressure.In addition, for the electric conducting material that is applicable to base material 10, can be by the current capacity of sealing as shown in Figure 2 to provide higher.The side bridge portion that extends and form the side of band in the side of band can be base material itself provides electrical connection, can increase the current capacity of coated conductor (band).
Although Fig. 2 do not show, conventionally need to be on whole superconductive tape, depositing noble metal layer on superconductive tape side particularly, the material of superconductor layer 14a and side bridge portion 20a and 20b (can be the base metal of above-mentioned copper or aluminium and so on) is isolated.
Fig. 3 has shown another execution mode of the present invention.Like this execution mode and Fig. 2 institute, structure is a bit similar, but forms bilateral structure, and this structure comprises the first resilient coating 12 and the second resilient coating 12b that is covered with respectively base material 10 first surface 11a and 11b.In addition, on the first covering layer 16a and the second covering layer 16b, add the first superconductor layer 14a and the second superconductor layer 14b.This special structure is by being all coated with superconductor layer 14a and 14b in base material both sides, thereby current capacity can be further provided valuably.
